What are the potential pitfalls of relying on error logging tools like Hoptoad/Airbrake in PHP development?

Relying solely on error logging tools like Hoptoad/Airbrake in PHP development can lead to overlooking important errors that are not caught by these tools. It is important to implement proper error handling within your PHP code to ensure all potential errors are captured and logged.

// Implementing error handling in PHP
set_error_handler(function($errno, $errstr, $errfile, $errline) {
    // Log the error using your preferred logging method (e.g. file logging, database logging)
    error_log("Error: $errstr in $errfile on line $errline");
});

// Triggering a sample error to test the error handling
trigger_error("This is a sample error", E_USER_ERROR);
